java多线程run方法传参

我们知道多线程是通过star()方法让线程处于准备就绪状态，而实际运行的业务逻辑是放在run()方法体中的，但是run()方法是没有参数的方法，实际的业务场景中，我们可能需要向方法体中传递参数，下面介绍常用的两种传参方式，第三种下次再说，或者你们百度吧，这里偷个懒。

第一种方式：构造方法传参

public class CallbackCustomerTypeThread implements Runnable { public static final Logger logger = LoggerFactory.getLogger(CallbackCustomerTypeThread.class); private BasCmCustomerType basCmCustomerType; private BasCmCustomerTypeService basCmCustomerTypeService; public CallbackCustomerTypeThread(BasCmCustomerType basCmCustomerType, BasCmCustomerTypeService basCmCustomerTypeService) { this.basCmCustomerType = basCmCustomerType; this.basCmCustomerTypeService = basCmCustomerTypeService; } @Override public void run() { //向金剑南同步 try { basCmCustomerTypeService.syncToJjn(basCmCustomerType); } catch (Exception e) { logger.info("向金剑南同步客户异常，id=" + basCmCustomerType.getId(), e); } //向水晶剑同步 try { basCmCustomerTypeService.syncToSjj(basCmCustomerType); } catch (Exception e) { logger.info("向水晶剑同步客户异常，id=" + basCmCustomerType.getId(), e); } } }

调用：

Runnable runnable = new CallbackCustomerTypeThread(basCmCustomerType, this); Thread thread = new Thread(runnable); thread.start();

第二种方式：通过变量或者方法传递参数

package mythread; public class MyThread2 implements Runnable { private String name; public void setName(String name) { this.name = name; } public void run() { System.out.println("hello " + name); } public static void main(String[] args) { MyThread2 myThread = new MyThread2(); myThread.setName("world"); Thread thread = new Thread(myThread); thread.start(); } }

第三种：通过回调函数传递参数
